JSON Utils
Unwrap escaped JSON inside string fields and inspect the resulting structure as formatted output and a tree.
Open JSON UtilsJSON-only toolkit
Toolbox Tools is built for developers and analysts who need quick answers from copied payloads, logs, and fixtures without sending data to a backend service.
The strongest workflows in this repo are the ones that help you inspect nested API responses, compare request and response bodies, and turn copied log fragments back into readable structures. That is why the homepage now points first to the JSON tools instead of presenting the site as a generic grab bag of utilities.
Core processing stays in the browser, so the normal cleanup and comparison flow works without an account, without a backend round-trip, and without making ad interaction part of the task.

Open JSON UtilsCompare two payloads and get deterministic field-level changes that are easy to scan or paste into tickets.
Open JSON DiffA common debugging path starts with a payload that was encoded once by an API and again by a log pipeline. JSON Utils is for that moment.
{"event":"webhook","payload":"{\"user\":{\"id\":42},\"flags\":\"[\\\"beta\\\"]\"}"}
After unwrapping, the same sample becomes readable structured data that you can inspect in one pass instead of manually removing escapes and reparsing nested values.
{
"event": "webhook",
"payload": {
"user": {
"id": 42
},
"flags": [
"beta"
]
}
}
Open JSON Utils when the payload itself is hard to read because arrays, booleans, or nested objects arrived as escaped strings. Open JSON Diff when both sides are already valid JSON and you want a stable change report.
Both tools are intended for direct debugging workflows: paste the sample, get a deterministic result, then move on.
This project is deliberately static and browser-only for core transforms. That keeps operating cost low, removes the need for account gates, and makes it easier to trust what the site is doing with copied debugging data.
You should still remove secrets before pasting production material, but the main cleanup and comparison work does not depend on shipping payloads to an application server.
The next product work is focused on making JSON Diff more useful for real debugging cases while keeping its output deterministic and easy to trust.
No new non-JSON tools are planned. The site is intentionally narrower now so the existing JSON pages can become sharper instead of broader.
